WINDOHW-SASH CASING.

SPECIFICATION forming part of Letters Patent No. 762,464, dated June 14,1904.

Application filed September 10, 1903. Serial No. 172,670. (No model.)

To all whom, it may concern:

Be it known that I, HENRY BORGMANN, a citizen of the United States,residing at VVashington, in the District ofColumbia, have invented a newand useful VVindow-Sash Casing, of which the following is aspecification.

My invention relates to window-sash easings, and has for its object toprovide a device of this character of simple construction which willpermit of the ready removal of the window for cleaning or otherpurposes.

To these ends the invention comprises the novel details of constructionand combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a side sectional elevation ofa portion of a window embodying my invention. Fig. 2 is a similar view,on an enlarged scale, showing the lower end of the movable section andits supporting means. Fig. 3 is a section on the line 3 3 of Fig. 2.Figs. 4, 5, and 6 are detail views. Figs. 7 and 8 are similar views ofthe sash-cord-holding device.

Referring to the drawings, 1 designates the upper and 2 the lowersectionsor sashes of the window, which travel, respectively, in a rearguide 3 and front guide 4, provided in the easement 5, these partsbeing, except as hereinafter specified, of the usual or any preferredconstruction and material.

The guide 4 consists of a rear wall formed by the division-strip 6, afront wall formed by the front molding 7, and an end wall 8, form-' ingthe front Wall of a weight opening or channel 9, provided in theeasement and separated into two compartments by a partition 10, attachedin any suitable manner to the rear wall 11, the said compartments of thechannel being designed for the weights of the upper and lower windowsections, respectively. The end wall 8 of the guide is made up of alower fixed section 12, an upper fixed section 13, and an intermediatemovable section 14 of a length slightly greater than the height of thewindowsection 2 and meeting the upper and lower sections, with which itis vertically alined by miter-joints 15. The division-strip 6,constituting the rear wall of the guide, is also provided with a movablesection 16, attached to and carried by the section 14, while the frontmolding 7 projects at its rear end into the path of and constitutes astop 17 for limiting the outward movement of the section 14.

The movable section 14 is held in engagement with the fixed sections 1213 and is movably sustained by a pair of devices 18 19, engaged,respectively, with the upper and lower fixed sections. As thesesupporting devices .are identical in construction and operation, I

will describe but one in'detail, in which 20 indicates a primary memberin the form of a tubular barrel or thimble extending transverselythrough the wall of the fixed section and having at its forward end aperipheral outstanding flange 21, which limits its rearward movement, atits rear end a longitudinal inwardly-extending opening or recess 22, and111 its front wall a central keyhole-opem ing 23, the purposes of whichparts will pres I ently appear.

24 indicates the secondary member of, the Supporting device, said memberbeing preferably composed of a cylindrical head or portion 25, having acentral internally-threaded opening 26, which vnormally alines with theopening 23, and a right-angularly-extending arm or portion 27, whichextends to the movable section 14 and is attached to the latter I theopening 26, said screw being provided at its outer end with a wing-head31, having a tool-seat32. The head 31 lies within a cavity or socket 33,provided for its reception at the outer end of .member 20, while uponthe screw 30 is a lateral lug or projection 34, spaced from the head 31and designed to bear upon the inner face of the end wall of member 20.It is obvious from this construction that when the screw 30 is rotatedeither by engagement of the fingers of the operator with the head or ofa tool with the seat 32 the member 24 will be moved outward, carryingwith it the section 14 of the guide, to the position indicated by dottedlines in Fig. 2, when the section 16 of strip 6 will be moved from itsposition in rear of sash 2, thus permitting of the latter being shovedinward at one side and readily disengaged from the guide at the oppositeside of the easement, said latter guide being, of course, of the usualconstruction.

It is to be understood, of course, that for moving the section 14 inwardboth of the devices 18 19 will be manipulated in the manner justexplained and that when the section moves inward such movement will belimited by an adjustable stop 35, preferably in the form of anangle-screw engaged with the lower fixed section 12, this screw being inalinement with the weight-channel partition 10, whereby it will be outof the path of and will not interfere with the movements of the weights.

To insure the window-section 2 when removed from the casing beingreadilyfreed from its weight-cords, I provide, as illustrated in Figs. 7and 8, a weight-eord-engaging device in the form of a short tubularmember 36,designed to be driven horizontally into the side bar of thewindow-sash, said member being provided with a circular cord-receivingopening 37, having a lateral tangentially-disposed entrance mouth orslot 38. In attaching the cord (indicated by dotted lines in Fig. 8) Iform at its outer end, as usual, a knot, which when the cord is passedthrough slot 38 to opening 37 lies beneath the latter within the member.

In practice the member 20 is locked against non-rotation by pin 40, andthe longitudinal slot 22 receives the arm 27 of member 24 when the partsare in normal position, so that by making the slot, as herein shown, ofa depth considerably greater than the thickness of the arm the device isadapted for attachment to casings in which the wall 8 varies inthickness.

From theforegoing it will be seen that I prodnceadevice of simpleconstruction which will be eflicient in operation and permit the readyremoval of the window-section. In attaining these ends I do not limitmyself to the precise details herein set forth, inasmuch as minorchanges may be made therein without departing from the spirit of theinvention.

Having thus described my invention, what I claim is l. The combinationwith a window and its casing, of a sash-guide carried by the latter,said guide having a movable section operable for permitting removal ofthe sash, and devices for movably sustaining the section, said devicescomprising each a tubular member associated with the casing, a memberassociated with the section and having an internallythreaded opening,and a screw connecting said members.

2. The combination with a window and its casing, of a sash-guide carriedby the latter, said guide having a movable section operable forpermitting removal of the sash, a member associated with the section andcomprising an internally-threaded head and an attachingarm, a tubularmember associated with the casing to receive the head and having alongitudinal recess for entrance of the arm, and an operating-screwconnected with the tubular member and in threaded engagement with thehead.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

HENRY BORGMANN.
